BACKGROUND OF THE INVENTION
The present invention relates to a startup method of a personal computer having various application programs (herein, simply referred to as applications), and more particularly to a startup method limited to a specific application and function.
[0002]
[Prior art]
In recent years, personal computers having a music CD playback function have been put into practical use. As a conventional example of such a personal computer, there is one having a dedicated operation switch for playing a CD in order to facilitate the use of the computer only as a CD player. For example, in the case of a laptop computer, a power switch, rewind switch, fast-forward switch, playback switch, and stop switch are provided on the front surface of the housing so that the display unit can be operated with the display unit closed, as in a normal CD player. There is something. The power controller can control the CD drive separately from the computer main body, and can control the power of only the CD drive by operating a power switch dedicated to the CD. Therefore, the CD can be reproduced by turning on the power switch dedicated to the CD, ejecting the tray, mounting the CD in the tray, and turning on the reproduction switch. This makes it possible to start playing a CD in a short time without pressing the power switch of the computer main body and starting up the OS.

In recent years, video CDs and DVDs that have inherited the standard of music CDs (hereinafter referred to simply as CDs) have become widespread as video recording media, and CD / DVD combined drives that can use not only CDs but also video CDs and DVDs. PCs including are on the market. However, in a personal computer having a dedicated operation switch for playing a conventional CD, a CD can be played with only the dedicated operation switch without pressing the power switch of the main body. I couldn't play it without pressing the switch. This is because a playback application is required for playback of these video recording media. Therefore, it is necessary to start a necessary reproduction application after starting an operating system (hereinafter referred to as OS) by pressing the power switch of the main body.
[0004]
However, when the OS is started by pressing the power switch of the main unit, all devices including devices unnecessary for media playback are started up (power on, initial setting), so it takes time and power consumption. There was a point.
[0005]
This is not limited to the activation of a function related to media playback, and the same applies when only a specific application or function is desired to be activated.
[0006]
[Problems to be solved by the invention]
As described above, even when a conventional personal computer wants to start only a specific application or function (turns on only a specific device), it may be necessary to start up the OS and turn on all the devices. There is a problem that wasteful time and power consumption are required. For example, music recording media can be played by turning on only the power switch of the media drive without operating the power switch of the main unit, and operating the playback switch, but the video recording media can be played by operating the power switch of the main unit, Cannot play without starting up.
[0007]
An object of the present invention is to provide a personal computer that can activate a specific function in a short time.
[0010]
[Means for Solving the Problems]
In order to solve the above problems and achieve the object, the present invention uses the following means.
[0012]
The present invention relates to a main power switch for starting an operating system, a media drive capable of reproducing recording information of a video recording medium, a sub power switch for the media drive, and the sub power switch being on when the main power switch is off. And when the discriminating means discriminates the type of media loaded in the media drive and the discriminating means determines that the media type is the first media, power is supplied to the sound circuit. And when the media type is determined to be the second media, a power controller for supplying power to the CPU is provided. After the power is supplied to the CPU, the operating system is The second media is played by starting and starting a playback application. .

With reference to FIG. 2, the operation of the present embodiment relating to media playback will be described. First, in step S10, when the power source of the main body (CPU 10) is turned off, it is detected whether the power switch 24 of the main body is turned on or the power switch 26 dedicated to the drive is turned on ("1" position). When the power switch 24 is turned on, the OS 18 is activated by a signal from the power controller 16 to set the computer to an initial state (step S11). On the other hand, when the power switch 26 is positioned at “1”, the power controller 16, the switch controller 30, the dedicated power switch 26, and the dedicated operation switch 28 operate even when the CPU 10 is not turned on. The power controller 16 supplies power to the CD / DVD drive 32 and the media controller 38.
[0038]
In step S <b> 14, the media controller 38 determines whether a medium is loaded in the drive 32. If no media is loaded, in step S16, the tray is ejected to prompt the user to load the media. When the installation of the medium is detected, in step S18, it is determined whether the medium type is a music medium (for example, CD) that does not require a playback application or a video medium (for example, DVD) that requires a playback application. To do.
[0039]
If it is a CD, the power supply controller 16 supplies power to the sound circuit 42 in step S20. When the operation of the playback switch is detected in step S22, the media controller 38 issues a playback command to the CD / DVD drive 32 in step S24. The drive 32 receives this command and plays the CD in step S26. CD playback is continued until the drive-only power switch 26 is changed to the power-off position ("0" position) as shown in step S28. Note that CD playback ends even when the power switch 24 of the main body is turned off.
[0040]
On the other hand, if the mounted medium is a DVD, in step S30, the power supply controller 16 supplies power to the CPU 10 to start the OS. When the OS is activated, all devices are powered on. Thereafter, devices unnecessary for DVD playback (for example, the other interface 44) are set to the power saving mode. In step S32, when the DVD playback application is activated and the operation of the playback switch is detected in step S34, the DVD is played back in step S36. DVD playback does not end even when the drive-only power switch 26 is changed to the power-off position ("0" position) as shown in step S38, and continues until the DVD playback application ends.
[0041]
As described above, according to the present embodiment, power can be supplied to the drive 32 by the power switch 26 dedicated to the drive 32 even when the power switch 24 of the apparatus is off (the CPU 10 is not powered on). When the medium is a CD, a reproduction command is supplied to the drive when the reproduction switch is turned on to reproduce the CD. When the medium is a DVD, the OS is started when the power switch 26 is turned on. However, a device unnecessary for DVD playback is set to the power saving mode, and a DVD playback application is started by turning on the playback switch, and DVD playback is performed.
[0042]
